A sure sign of Spring has found it’s way into my kitchen. Rhubarb is finally in-season!

I finally got my hands on some fresh rhubarb, thanks to my friend Melissa! Rhubarb is the one fruit I eagerly anticipate every Spring. I love the sweet/sour tartness of the crisp, delicious stalks of fruit. My favorite thing as a kid was to pick it fresh and dip it into a bowl of sugar. A little bit of sugar with each bite!

Every time I get my hands on some rhubarb I always seem to make it into a crisp. The crumble of the oatmeal and brown sugar with the tartness of the rhubarb just go so well together. I wanted to keep that same combination but have it in a bar form so that it would be easy to pack in the kids lunches. These Rhubarb Crumble Bars were the perfect solution.

When I finished making these bars I cooked up some leftover rhubarb so that my kids could try how delicious it is. One taste of the stewed rhubarb and they were asking for more! Since it’s only the beginning of the season I know I’ll be cooking and baking with it a lot more!
